Abstract
The utility model relates to a locking device for antiskid chain of wheel. A ratchet non-return mechanism which comprises a ratchet, a non-return pawl, a pawl sleeve, a spring, and a lifting hook is arranged in a case. A peripheral V-shaped groove is arranged on a ratchet wheel hub, and four radial holes are arranged on the bottom of the V-shaped groove. The both ends of four steel ropes which goes through the radial holes are penetrated from the case and tightened with an anti-skid chain. An axial screw hole is arranged on one end of the ratchet which is near the V-shaped groove. The steel ropes can be jammed by a screw bolt arranged in the axial screw hole. Pulling the screw bolt so as to drive the ratchet wheel to rotate, twisting the steel ropes in the V-shaped groove, tensioning and fixing the antiskid chain on the wheel, and when the screw bolt stops to be pulled, the non-return pawl can automatically stops the ratchet under the action of the spring, achieving the goal of locking the antiskid chain of the wheel. When the lift hook is lifted, the antiskid chain can be disassembled.
Description
The utility model relates to a kind of vehicle wheel non-slip device, especially can be more convenient, more firmly existing various anti-slipping chains are fixed on a kind of latching device on the wheel.
At present, known anti-slipping chain device is that a kind of purpose made chain is wrapped on the wheel, and then with iron wire or leather strap etc. it is tightened.Fixedly anti-slipping chain has many shortcomings in this way, and the one, loading and unloading are inconvenient, moreover are the bad control of tightness, to making loosening easily in the process of moving and coming off.
The purpose of this utility model provides a kind of latching device, and it can be securely fixed in anti-slipping chain on the wheel, and easy to loading and unloading, and degree of tightness is adjustable.
The utility model is achieved in that in shell, ratchet, check pawl, ratchet cover, spring, lancet are formed a secondary ratchet non-return mechanism, there is boss at the ratchet two ends, rotating shaft as ratchet is installed in the concave station of shell, and this concave station is as bearing, in a side of ratchet one circumferential V-slot is arranged, there are 4 radially to through hole in the V-slot bottom, wear 4 steel ropes in this radial hole, the two ends of steel rope pass from the slotted eye on the shell, fasten with anti-slipping chain, end at the close V-slot of ratchet has an axial screw, bolt in the screw is the steel rope jam-packed, and it is consistent that the direction of feed that turns to ratchet during ratchet locking and the bolt in this axial screw screw direction, like this, cw is pulled the bolt of ratchet shaft in screw, just can rotating ratchet, in V-slot, anti-slipping chain is strained gradually by steel rope with the steel rope strand, when anti-slipping chain is tightened to a certain degree, stop wrenching bolt, check pawl just under the effect of spring, stops ratchet automatically; Thereby locking anti-slipping chain.When unloading anti-slipping chain, as long as lancet is mentioned.
Adopt such scheme, make the fixing of anti-slipping chain, loading and unloading have all realized mechanization, and simple in structure, easy to operate.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the front view of the utility model structure.
Fig. 2 is the cutaway view of the utility model structure
1 lancet among the figure, 2 ratchet covers, 3 springs, 4 check pawls, 5 shells, 6 ratchets, 7 bolts, 8 steel ropes, 9 shells, 10 axial screws, 11 radial holes, 12 shell slotted eyes.
In embodiment as shown in the figure, shell (5), (9) be flanged garden dish type drawing part, the heart all has the concave station of an outward bulge therein, also has hole, a garden at the center of shell (9), 8 semi-round grooves are all arranged on flange, the flange of shell (9) is bigger than the flange of shell (5), there is the otch slightly wideer than semi-round groove diameter in place in the outer end of the semi-round groove of shell (9) greater than the flange of shell (5), with shell (5), (9) semi-round groove to semi-round groove altogether, just in shell (5), 8 slotted eyes (12) are arranged, again with the flange of the flange flange inclusion shell (5) of shell (9) on the faying face (9).In shell (5), (9) in, the boss at ratchet (6) two ends is installed in shell (5) as rotating shaft, (9) in the concave station, ratchet (6) has a circumferential V-slot near a side of shell (9), there are 4 radially to through hole (11) in the V-slot bottom, axis of this radial hole (11) and shell (5), (9) on the faying face axis of slotted eye (12) in same plane, wear 4 steel ropes (8) in radial hole (11) lining, the two ends of steel rope (8) are from shell (5), (9) slotted eye on (12) passes, fasten with anti-slipping chain, at the end of ratchet (6) near V-slot, one axial screw (10) is arranged, the degree of depth of this screw arrives till the radial hole (11), and bolt (7) is arranged in the screw.Ratchet cover (2) is riveted on the shell (5), check pawl (4), spring (3) all is installed in ratchet cover (2) lining, and the cross section of check pawl (4) is a rectangle, and the one end is the inclined-plane, the angle of inclination is consistent with the gear teeth flank of tooth of ratchet (6), and under the effect of spring (3), keep in touch with the gear teeth flank of tooth of ratchet (6), lancet (1) is from shell (5), ratchet cover (2) pierces into, and is installed on the check pawl with screw thread.
